Classical quantitative genetics and quantitative trait dissection analysis (QTL) approaches were used in order to investigate the genetic determinism of wood cellulose carbon isotope composition (δ 13 C, a time integrated estimate of water use efficiency) and of diameter growth and their relationship on adult trees (15 years) of a forest tree species (maritime pine). A half diallel experimental set-up was used to (1) estimate heritabilities for δ 13 C and ring width and (2) to decompose the phenotypic δ 13 C/growth correlation into its genetic and environmental components. Considerable variation was found for δ 13 C (range of over 3%‰) and for ring width (range of over 5 mm) and significant heritabilities (narrow sense 0.17/0.19 for δ 13 C and ring width, respectively, 100% additivity). The significant phenotypic correlation between δ 13 C and ring width was not determined by the genetic component, but was attributable to environmental components. Using a genetic linkage map of a full-sib family, four significant and four suggestive QTLs were detected for δ 13 C, the first for δ 13 C in a forest tree species, as far as known to the authors. Two significant and four suggestive QTLs were found for ring width. No co-location of QTLs was found between δ 13 C and growth.

- Drought responses by individual tree species are not often correlated with tree species diversity in European forests (2016, unknown): “…including radiation, soil fertility (Farquhar, Ehleringer & Hubick 1989; Warren, McGrath & Adams 2001; Ferrio, Voltas & Araus 2003), and genetics (Brendel et al. 2002), it was assumed that the main factor that varies between the wet and dry year is the water-related stress (see (Grossiord et…”
